Customer emails

“A software developer by trade, I often write my own scripts to automate tedious tasks in order to have the best control over the end result. After many hours of working on my own and pulling in several open source alternatives, I purchased Duplicate Annihilator for less than $10. Not only has this program identified my iPhoto duplicates MORE ACCURATELY than what I produced after hours of manual and script editing, but it did so with no supervision. An excellent product and great support. I highly recommend this product to anyone who wants to enjoy their photos instead of organizing them.”

“I just wanted to write to you about how much work and grief you saved me. Throughout the years of multiple iPhoto upgrades and rebuilding photo libraries I ended up with over fourteen thousand photos and I knew that many of them were duplicates but I was too lazy to deal with them.

Well, then came a hard drive crash and the prospect of me rebuilding my library once again (I didn't have a very good strategy for backups but I do now) and going through each and every photo to figure out which ones were originals. After a few hundred of these I got frustrated and found your programs and figured that for less than eight bucks I'd give it a shot.

Best eight dollars I've ever spent. (The library went from 14,647 to 7,408.)

I got a new computer and in the process of transferring data from old to new I ended up with many duplicates. Even one photo of my boyfriends mother is more than enough but 5??? ARGGHHH!

In less time than it took to order and install Annihilator, 1,254 duplicates were gone. I love how you set the app to 'label' photos as duplicates in comments, so easy to manage them that way! And it makes searching and deleting very easy. I also like getting the registration # immediately on completing order & followed up in confirmation email... I can think of another company or two who would benefit from doing it this way!

thanks again, I can once again go into iPhoto without fear of total depression :-)”

“It's been just over a week since I got Duplicate Annihilator, and I just wanted to send you a thank you note to say that I am so happy that you created your software. Apple should really adopt the program and add it to iphoto cause it really cleared up a NIGHTMARE for me.

I have a mac. About a year ago, one of my 4 kids was into gaming, and decided one day to split my hard-drive in half and put windows on one of the halves. (without my blessings, I might add) Well, he rushed through it I guess, and ended up accidentally deleting my entire operating system. When I came home, there was an empty hard-drive and the windows picture on the screen.

Anyway, a friend of ours kindly volunteered to recover the lost data using a recovery program (Disc Doctors), and when he came to the photo part, I guess rather than recovering the "originals only", he chose to recover all images. This meant every thumbnail, every duplicate (which technically are not duplicates because they have different file names and sizes in many cases) every image that the computer had ever seen -Including internet images!-, all came back on our computer... All 45,000 of them! (The library before the crash numbered about 4400.)

I had to go out and buy an external hard-drive (which was good, cause now I back up regularly) just to house iphoto.

I started running your programs as soon as I got them, and after several days my iphoto library was reduced to just over 5000 photos. There still are a few duplicates there, but I didn't expect 100% perfection. Now iphoto's back on my computer and I've got some sorting to do, but basically, because of your software, the nightmare's over.

So thanks. And congratulations for believing in something strongly enough to stick to it and make it go from being just an idea, to a great thing that people can use. ”
